WALL CONSTRUCTION.

@riginal application aled November 9, 1911, Serial No. 659,298. Divided and this application led .Aiig'ustA 7, 1912. Serial No; l$13,900.

lo all 'whom it may concern Be it known that I, JOHN E. CONZELMAN, a citizen ofthe United States, residing at the city of Webster Groves, in the county of St. Louis and 4State of Missouri, have invented certain new and useful Improvements in Wall Construction, (Case A,) of which the following is aspecication.

This application is a division and continuation ofv one led by me November 9,

be hereinafter more fully described and pointed out in the claim.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation of part of a wall embodying this invention and including two columns and wall slabs-connected therewith; Fig. 2 is a sectional View on the line 2-2, Fig. l; Fig. 3 is a sectional view on the line 3 3, Fig. l; and Fig. 4 is a fragmentary perspective view of the form of slab used in this construction.

Each panel of the wall consists of a pair of columns or uprights l anda plurality of vertically-disposed slabs 2, the ends of which lit in grooves 3 in the sides of said columns. Each slab 2 is preferably formed with a rectangular configuration, and has a hollow tile 4 or a plurality of such tiles embedded therein, so as to lalord an air-space in same. Said tiles 4 extend vertically in the slab 2 and the upper ends thereof project above the top of said slab, an opening or groove 5 being left below the lower ends of said tiles in the bottom of said slab. By this arrangement, when the slabs 2 are placed one on top of another between the columns l, the ends of said slabs ft in the grooves 3 in said columns, as best seen in Fig. 3, and the upper ends of the til-es 4 in each slab 2v fit in the opening or groove 5 in the bottom of the next slab 2 above same, so that the tiles 4 in said slabs register substantially in vertical alinement.

The columns 1 are preferably supported on a foundation 6, which extends undern eath the lower slabs in each panel, and a rlb 7 on said foundation fits in the opening or groove 5 in the bottom of the lower slab 2. If desired, the adjoining edges of each two adjacent slabs 2 and the ends of saidslabs may be buttered with grout just previous to the placing of said slabs in position in the wall, so that when said grout sets,

s'aid slabs are united integrally and said wall is light in weight and renders the space or room inclosed thereby moisture proof. By reason of the tiles 4 being arranged to project above the top of each slab and, also, to leave an opening or groove 5 in the bottom of said slab so that the slabs can be united by tongue-and-groo-ve joints, the 'unctures are thereby made secure and dura- Furthermore, the slabs and columns coperate and are interengaged to form a rigid, secure and lasting structure.

I claim:

In concrete slab construction, a series of superimposed slabs, each slab consisting of a concrete body of rectangular cross section having a series of transverse similar hollow tiles embedded therein, each tile being of rectangular crosssection and having their sides arranged in contacting engagement throughout, one of the ends of each of the tiles extending beyond one side of the body to form a single tongue of rectangular cross section having straight uninterrupted sides and a straight uninterrupted top face, vthe opposite ends of the tiles being disposed in spaced relation to the opposite side of the body whereby to provide a single opening at said opposite end of the body, which opening has substantially the same rectanand whereby the openings of the tiles will guiar cross-section as that of the tongue and register.

has a straight uninterrupted bottom face In testimony whereof I hereunto aix my formed by said `opposite ends of the tiles, signature in the presence of two witnesses.

whereby When the tongue of a slab projects JOHN E. CONZELMAN.

into the opening of an adjacent slab the top Witnesses face of the tongue will directly seat on'the GEORGE G. ANDERSON, adjacent ends of the tiles in an adjacent slab, l WALTER C. GUELS.
